P/E Ratio Calculator
Calculate price-to-earnings ratio for stocks
About this calculator
The P/E Ratio Calculator helps investors evaluate stock valuation by determining the price-to-earnings ratio, which compares a company's current share price to its earnings per share. This fundamental metric indicates how much investors are willing to pay for each dollar of earnings, making it essential for investment decisions. A lower P/E ratio may suggest an undervalued stock, while a higher ratio could indicate overvaluation or high growth expectations.
How to use
Enter the current stock price and the earnings per share (EPS) into the calculator. The tool will automatically compute the P/E ratio by dividing the stock price by the EPS. Compare this ratio with industry averages and competitors to assess whether the stock is fairly valued.
Frequently asked questions
What is a good P/E ratio?
There's no universal 'good' P/E ratio as it varies by industry. Generally, ratios between 15-25 are considered reasonable, but growth stocks often have higher ratios.
Can P/E ratio be negative?
P/E ratios are undefined when earnings are negative. Companies with losses don't have meaningful P/E ratios, so other valuation metrics should be used instead.
Should I use trailing or forward P/E?
Trailing P/E uses past 12 months' earnings, while forward P/E uses projected earnings. Both are useful - trailing for historical performance, forward for growth expectations.
